The not opening position overlapping with ink jet recording head 1 during the 3rd direction D3 (Z-direction) top view in liquid injection direction.In other words
Say, the 1st conveying roller 211 is arranged at when from the 3rd direction D3 top view the not weight of circuit board 170 with ink jet recording head 1
Folded opening position.In other words, the conveying roller 211 of ink jet recording head 1 and the 1st is configured in the 3rd side as liquid injection direction
Mutually not opposite opening position on to D3.But details will be described further below, if the 1st conveying roller 211 is configured at
From being positioned away from from ink jet recording head 1 along conveying direction X, then the 2nd of the 1st conveying roller 211 and the 2nd supply unit 220 the is defeated
The conveying direction X of roller 221 interval is sent to become remote, the record sheet S kept between the 1st conveying roller 211 and the 2nd conveying roller 221
The fixation of posture become difficult.It is therefore preferable that the 1st conveying roller 211 is set close to ink jet recording head 1 as far as possible.In addition, example
Such as, the 1st conveying roller 211 is being configured at the position overlapping with ink jet recording head when from the 3rd direction D3 (Z-direction) top view
In the case of putting, can not ensure configuration be driven in the 1st conveying roller 211 the 1st driven voller 212 space, ink jet recording head 1 with
1st driven voller 212 can interfere.In addition, if ink jet type is recorded in order to ensure configuring the space of the 1st driven voller 212

It is right, if by the 2nd conveying roller 221 it is identical with the 1st conveying roller 211 be arranged on the 3rd direction D3 not with the phase of ink jet recording head 1
Opposed region, then the change of the distance of the 1st conveying roller 211 and the 2nd conveying roller 221 is remote, the 1st conveying roller 211 and the 2nd conveying roller 221
Between the record sheet S fixation of posture become difficult, produce landing positions skew and cause press quality to reduce, and nothing
Method carries out high speed printing.
In addition, if ink jet type is recorded in order to ensure the space of configuration guide member 222 and the 2nd driven voller 223
First 1 from supporting member 200 along the 3rd direction D3 configured separates, then liquid injection face 20a and record sheet S interval broaden, ink-jet
Formula tape deck I maximizes on the 3rd direction D3 (Z-direction), and produces the landing positions skew of sprayed ink droplet, produces
The defects of high speed printing etc. can not be performed.In the present embodiment, by not widening liquid injection face 20a and record sheet S's
Interval, will be in the 2nd region that conveying roller 221 is configured at ink jet recording head 1 is opposite, not relative with circuit board 170
The region put, it can be ensured that guide member 222 and the 2nd driven voller are configured between ink jet recording head 1 and record sheet S
223 space.
Specifically, as described above, the flow path features 130 of ink jet recording head 1 of present embodiment are compared to holding wiring base
Holding member 140 towards the 1st direction D1 of plate 170 D1A sides are protrusively provided.Therefore, the 2nd conveying roller 221 is in the 3rd direction D3 (Z
Direction) holding member 140 of flow path features 130 is opposite towards the region that the 1st direction D1 (X-direction) D1A sides protrude compared with
Configuration.That is, in the region that the holding member 140 compared to flow path features 130 protrudes towards the 1st direction D1 D1A sides and record sheet S
Between form space, therefore, it is possible in the space configure the driven voller 223 of guide member 222 and the 2nd.That is, present embodiment
Ink jet recording head 1, the width of flow path features 130 must be narrower than by the way that the 1st direction D1 of circuit board 170 width is formed
Degree, does not widen liquid injection face 20a and record sheet S interval, space is formed between flow path features 130 and record sheet S,
The driven voller 223 of guide member 222 and the 2nd can be configured in the space.On the other hand, for example, if by circuit board 170
The 1st direction D1 width to be formed with the identical width of flow path features 130, then need the maintaining part of ink jet recording head 1
1st direction D1 of part 140 width with the identical width of flow path features 130 to form.Therefore, it is impossible to ensure in circuit board
The space of the driven voller 223 of guide member 222 and the 2nd is configured between 170 and record sheet S.In addition, if in order to ensure configuration
The space of guide member 222 and the 2nd driven voller 223 and by ink jet recording head 1 and supporting member 200 in the 3rd direction D3 (Z
Direction) on configured separate, then liquid injection face 20a and record sheet S interval broaden, inkjet recording device I is in z-direction
Maximization, and produce the landing positions skew of ink droplet, the defects of generation can not perform high speed printing etc..In addition, though also examine
The interval for not widening liquid injection face 20a and record sheet S is considered, in order to ensure configuring the space of the 2nd supply unit 220, by the 1st
The wide circuit board 170 of direction D1 width is configured to be positioned away from the 3rd direction D3 from record sheet S, but this can lead
Ink jet recording head 1 is caused to be maximized on the 3rd direction D3.In addition, if by head main body 150 and the configured separate of circuit board 170,
It must then increase and connect their wiring part 121.Because wiring part 121 is the part of high price, if so increasing wiring
Part 121, then become high cost.
In the present embodiment, flow path features must be narrower than by the way that the 1st direction D1 of circuit board 170 width is formed
130 width, in the state of liquid injection face 20a and record sheet S interval is shortened, it can be ensured that configuration guide member
The space of 222 and the 2nd driven voller 223, and can be by circuit board 170 and head main body 150 in the 3rd direction D3 (Z-direction)
Upper close configuration.Therefore, it is possible to realize the 3rd direction D3's (Z-direction) of ink jet recording head 1 and inkjet recording device I
Minimize and wiring part 121 can be shortened so as to reduce cost.In addition, the 2nd supply unit 220 ink jet type is not arranged at
The outside of record first 1, the i.e. outside in opposite region in z-direction, can shorten the conveying of the 1st supply unit the 210 and the 2nd singly
The distance of member 220, and the liquid injection face 20a and record sheet S of ink jet recording head 1 interval can be shortened, therefore energy
Enough suppress the landing positions skew of ink droplet, and high speed printing can be realized.
In addition, in the present embodiment, the 2nd conveying roller 221 is arranged at the opening position opposite with flow path features 130, because
This, bows as top view 221 record sheet S of the 2nd conveying roller, from the 3rd direction D3 (Z-direction) as liquid injection direction
During depending on observation, the opening position overlapping with the runner of ink jet recording head 1 1351 is configured at.That is, as described above, being arranged at flow path portion
Channel forming member 135 on part 130 is the function for each function part for being internally provided with filter, valve element, heating unit etc.
Part, it is therefore desirable to have for configuring the region of each function part, pulling around towards the region of the runner 1351 of each function part.Cause
This, the direction D1 of flow path features 130 the 1st width is formed with the width bigger than holding member 140.Therefore, the 2nd conveying roller 221
Actually on the 3rd direction D3 (Z-direction) with the runner 1351 of flow path features 130 it is opposite configure.Can certainly basis
The configuration of runner 1351 and the 2nd conveying roller 221 is configured to position opposite with runner 1351 on the 3rd direction D3 (Z-direction)
